GUI thread detecting in the Qt library

Question

I need to know in the context of which thread my function is running, is it main GUI thread or some worker thread.

I can\'t use a simple solution to store QThread pointe

Answer 1

If you have Qt in the lib you can ask for the thread of the application object. The application object is alway living in the main gui thread.

void fooWorker()
{
    const bool isGuiThread = 
        QThread::currentThread() == QCoreApplication::instance()->thread();

}
